PICK.

To all whom t may concern Be it known that l, FILO S. STEVENS, a citizen of .the United States, residing at Ashville, in the county of Chautauqua and State of New York, have invented certain new and usci'ul Improvements in Picks, of which the following in a specification.

Thisinvention relates to an improved pick, andthe principal object of the inven.` tion is to provide a pick in. which the handle and head are so constructed that the head may be readily removed from the handle for sharpening or for the purpose of replacing a di'erent type of pick head, and to provide an improved type of pawl for releasablyv holdingthe `pick head in place,

the pawl and pick head being so constructed v y clme of the inner walls 13 by notches 12 so that the head will be tightly wedged in place.

Another object of the invention is to provide a pawl which will be very strong and durable and which will not be liable to break or work loose.

Another object of the invention is to so construct the pocket in which the pawl is pivotally mounted that the spring which yieldably holds the pawl in the normal position will be securely held in place.

This invention is illustrated in the accompanying drawings wherein- Figure 1 is a view in elevation showing the pick head in the handle with the pawl removed; Fig. 2 is a section taken along the line 2 2 of Fig. 1 with the pawl in place; Fig. 3 is a perspective view of the pawl; Fig. 4 is an elevation of the central portion of the pick head.

The pick head 10 has its outer face provided with a centrally located cut-out portion forming abutment shoulders 11 which are positioned upon opposite sides of the handle when the pick head is in place and serve to prevent longitudinal movement of the pick head. Upon the side of the pick head notches 12 are formed, the inner walls 13 of the notches being inclined as shown in Fig. 4 so that the pawl will have a tendency to move the pick head toward the outer end of the handle and cause the outer end of the handle to be seated between the abutment shoulders 11. The handle 14 has its outer end portion provided with a transverselyextending opening 15 which forms the pocket through which the pick h ead passes and is also provided with a longitudinally- Specification of Letters Patent.

tom of the chamber 16 is cut at an incline so that' the .pawl may be rocked upon its pivot pin 20 a suliicient distance to move its arms 21 out of engagement with the pick head. These arms 21 which extend through the slots 22 have their free end portions provided with inwardly extending heels 23 which extend through the notches 12 to removably'hold the pick head in place. It should be noted that the ends of the arms are cut at an incline conforming to the inthat 'when the spring moves the pawl to its locked position, the arms of the pawl will move the pick head to a position in which the abutment shoulders 11 will engage the end of the pick head. It should also be noted that this pawl by fitting into the notch 12 will prevent longitudinal movement of the pick head.

rIhe operation of this pick is very simple. When it is desired to insert the pick head, the pawl is moved to raise the arms thus permitting the pick to be passed into the opening 15. After the end of the pick has been inserted in the opening between the arms, thepick head can then be moved through the opening until the notches 12 reach the heels 23. rThese heels will then drop into the notches and will move them outwardly to the position shown in Fig. 1 with the outlet end of the pickhandle positioned between the abutment shoulders 11. By having the handle lit between the abutment shoulders, the strain is partially removed from the heels 23 and therefore when using the pick, there is no danger of the heels being broken. When it is desired to remove the piclr head to sharpen the same or to insert a pick head of a dierent size or type, the pawl is moved to raise the arms and the pick head can then be easily withdrawn.

There has thus been provided an improved pick in which the pick head is removably connected with the handle and in which the pick head will be securely held in place. There has also been provided an improved fastening means for the pick head which is so constructed that the pick head Patented Aug. 3, 1215." Application led March 4, 1914. Serial No. 822,382. i

will be preventedfrom working loose and y which will move the pick head to such a Vpo-- sition that the outer endportion of the handle will it between the shoulders formed upon the pick head thus preventing the se,- curing means from being broken when the pickis in use. Y

What is claimed is:

1. In a tool of the character described' a handle provided with an opening and with a recess formed in one side of the handle and communicating with said opening, the bottom of said recess` having a well formed therein, a cutting element passing through said opening andhaving its outer face provided with abutments positioned upon opposite sides of said handle and having its inner face provided with notches having inclined inner walls7 a pawl pivotally mounted yin said recess and provided with arms extending into said opening and having their free ends provided with inclined inner ends and with heels extending into the notches of said v -cutting element, and a spring mounted in Copies of this patent ma;r be obtained for handle provided with a transversely extending cutout, a head extending through said cutout and pro vided with notches in one side face having inclined inner Walls forming Vcam surfaces, abutment shoulders extending from the opposite wall of said head for engaging opposite sides of said handle, a pawl carried by said handle and provided with teeth passing into said notches and engaging the inclined inner wall thereofl Jfor moving ,Said head into a position to bring said abutment shoulders into engagement with said handle, and means for releasably holding said pawl in an operative position.

In testimony whereof I atiix my signature in presence of two witnesses.
